how or correct 404 error...

Hi,

I have checked DB and seen that I have a lot of 404 errors because a file/font is not found.
The urls are :
/wp-content/fonts/fontawesome-webfont.woff2
/wp-content/fonts/fontawesome-webfont.ttf
/wp-content/fonts/fontawesome-webfont.woff
It is not inside a plugin or theme.

How can I get rid of this?

Thanks
